Flamingos are born white, but they turn pink because of the food they eat; this is an example of how
environment, a physical factor, can affect phenotypes.
<span>The phenotype is the visible physical or biochemical characteristic of an individual organism which is determined by both genetic factors (genotype) and environmental influences. There are many e</span><span>nvironmental factors and they include diet, climate, illness and stress. If environmental factors have a strong influence this means the phenotypic plasticity is high (capable to change).</span>
Answer:
deletion of a chromosome.
Explanation:
Changes usually occur in the nuclear material (chromosomes) of a cell. These changes are called MUTATION. A mutation, depending on how it occurs, consists of different types. Mutation can result into deletion of a chromosome or addition of a chromosome.
Deletion mutation is the removal of a part of the chromosome segment or chromosome while Insertion mutation is the addition of a part of the chromosome segment to the original chromosome. Both insertion and deletion can be detrimental to the organism as it can lead to the serious genetic disorders, however, deletion of a chromosome has the most adverse effect.
During deletion mutation, information encoded in a particular chromosome is lost completely which can make the resulting individual deficient of certain traits that makes him/her normal but in Insertion mutation, a different chromosome is added which can sometimes be beneficial to the resulting organism e.g can confer resistance to certain unfavorable condition.
Answer:.
A test-cross can reveal an unknown genotype. As the plants are heterozygous they sort independently of each other. when they are cross linked dominant genes express themselves in most of the cases whereas the recessive genes also express themselves resulting in the formation of tall and yellow plants and as well as short and green plants.
Explanation:
The impact of a single gene on more than one characteristic is called pleiotropy. Mendel deduced from his results that each individual had two discrete copies of the characteristic that are passed individually to offspring.Mendel called the dominant allele the expressed unit factor; the recessive allele was referred to as the latent unit factor.Mendel’s law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. The recessive trait will only be expressed by offspring that have two copies of this allele and these offspring will breed true when self-crossed.
